What to know about Quantum Networking

Researchers from NIST, the Joint Quantum Institute, and Qunnect successfully transmitted entangled photons over 62 kilometers of existing aerial fiber-optic infrastructure. The study demonstrates that quantum networking protocols can function in noisy, real-world environments by using real-time polarization stabilization.

What happened

'Spooky' particles transit DC suburbs, a step toward a quantum network Robert Egan Senior Editor In early 2025, special signals wended their way through a fiber-optic highway strung above the streets and sidewalks of the Maryland suburbs.

Why it matters

The arrival of those signals at their destination marks a significant step toward a long-held dream of building a "quantum network." Researchers believe that this emerging technology could someday link quantum devices in ways that supercharge scientific…

Common ground

National Institute of Standards and Technology (NIST) researchers and collaborators reported this advance in the Journal of Optical Communications and Networking.
